Suggest supporting frame rate adjustment #101

Open fcwys opened 1 month ago

At present, it has been found that in remote desktop environments, the refresh rate of the screen is relatively slow, and the display of QR codes lags and affects the recognition of the APP. It is hoped that the frame rate can be adjusted to adapt to this usage scenario.

This probably isn't the best answer, but right now the easiest way to do this might be to crack open whatever version of the cimbar.js page you're using and find/modify this line: https://github.com/sz3/libcimbar/blob/master/web/main.js#L3

That "66" is milliseconds -- the delay between frames. I'm not sure what frame delay will work best for that use case -- or even if there is a one-size-fits-all framerate, but you might try something like 200 (5 fps), 100 (10 fps), or something in between and see if it helps.

OK, thank you. We can consider adding a frame rate option to the web page later.
